Understanding Atmospheric Perspective In Art

Like many subjects in art, landscape paintings can tell a story, taking the viewer to a different place and time. Whether the place is real or imaginary, it should be convincing, making us feel as though it perhaps could exist, even if only within our minds. Putting the rules of perspective into good use can help make that happen. One-point and two-point perspective are crucial basics to understand, as well as atmospheric perspective.

What is atmospheric perspective? It’s the effect or illusion that light, shadow and the atmosphere have on your subject. Landscape paintings look softer, perhaps more hazy or even dreamlike, when they incorporate atmospheric perspective. Michael Reardon, author of Watercolor Techniques, gives his explanation of perspective in art in this excerpt from his popular book. ~Cherie

To do a basic drawing in perspective requires two elements: a horizon line and vanishing points. Some drawings require only one vanishing point (one-point perspective) while others require two or more.

The horizon line is simply a horizontal line across the page that corresponds to your eye level. Think of a view of the ocean. The far horizontal line is the horizon, hence a horizon line. A similar unseen line exists in all paintings in perspective.

Lines that converge at the vanishing point(s) create the illusion of perspective. Put simply, all of the lines of one side of a building radiate from one vanishing point, and the lines on the other side converge on the other vanishing point.

Many images, such as cityscapes, often only have one vanishing point. These are known as one-point perspectives. The second vanishing point is so far away that all of the lines are horizontal.

Two-Point Perspective in Art

In this eye-level view (Mission Dolorses, San Francisco, at right, and sketch, above) you can clearly see the eye-level line of the horizon line. In such a view, all of the heads of the people are at or near the horizon line.

Note how all of the lines on the left side of the buildings converge at the left vanishing point and how the right side lines converge on the right vanishing point.

I always do a quick pencil study before I paint to determine the horizon line and vanishing points.

One-Point Perspective in Art

The vanishing point in a one-point perspective falls within the borders of the image. Consider the vanishing point in Gold Gate Bridge Overlook (above). The left vanishing point is so far to the left that the lines look horizontal.

The horizon line is at eye-level for a person on the bridge. The vanishing points for the fort below also fall on this elevated horizon line. Note how the heads of the distant people touch the horizon line.

One-point perspectives are especially useful in street scenes, with buildings receding in the distance toward a single vanishing point.

What is Atmospheric Perspective?

Perspective is a means to create the illusion of depth in an image. According to Leonardo da Vinci, there are more ways to imbue your artwork with a sense of space than the linear perspective discussed above.

Leonardo da Vinci wrote extensively on perspective. He considered atmospheric perspective on a par with linear perspective. By making your backgrounds more ethereal you can, like da Vinci, accentuate the depth in your watercolors.

Note how the backgrounds in Filbert Street, San Francisco and Market Street, San Francisco are less defined. In reality, there was considerably more detail in the backgrounds, but I simplified them as shapes. This lack of definition helps to set off the more carefully rendered foregrounds and middle grounds. ~Michael
